Letters Patent No. 99,068, dated January 55,1870.

COFFEE-POT ATTACHMENT.

1 The Schedule referred to in these Letters Patent and making part of the same.

.scription thereof, reference being had to the accompanying drawings, making part of this specification, consisting of a single figure, showing my attachment within a cofiee-pouready for use, all being shown in section.

To enable others skilled in the art to make and use my attachment for cofiee-pots, I proceed to describe the construction and operation of the same.

, The several parts maybe made of tin.

The lower part A consists of two pieces, the top g being a disk of metal, having a small orifice, h,'in the centre, and the side piece f is about one inch in width, and is securely fastened to g.

The diameter of g is a little less than the diameter of the top of the coffee-pot with which the attachment is to be used.

The partA is open at the bottom.

0 is a tube, soldered to g, around the orifice h.

B is a receptacle for the ground coffee.

As shown in the drawings,'the bottom and the lower portion of this receptacle are made of perforated tin 1', while the upper part is made of common tin. v

The bottom of the receptacle has an orifice, around which is soldered the tube 12, which is a little larger than 0.

The receptacle B rests upon a collar, a, which is secured to the tube 0. t

E is the flange of the cover of the cofiee-pot, and is no part of my device.

0 is a short tube, which fits over 0.

.e. c are two short strips of metal, fastened to c, and support the defiector'd, which is secured to the strips cc.

The diameter of B is a little less than that of the cofi'ee-pot with which it is to be used.

In use, my attachment is placed within the coffeepot, with which it is to be used, with therequisite The ground coifee is then put into as set forth.

the receptacle ,Bfand the coffee-pot is placed where the water will boil. When boiling, hot water will be forced from within A, upthrough the tube 0, and, striking against the deflector d, will be showered upon the ground coffee in B, which operation will continue so long as the boiling continues.

It is obvious that when this device is used, cold water may be put into the coffcevpot, and it will not come in contact with the cofl'ee until it boils ,-o r, if desired, hot water may be used at first, being poured upon the ground coffee in -B. In either case, the boiling may be continued until the strength of the cofi'ee has been sufficiently extracted.

The receptacle B may be made without any perforations in the side.

My device can be made of various sizes, and put upon the market detached from the cofi'ee-pot, and parties can use it without being at the'expense of purchasing new coffee-pots.

It can be readily removed from the coffee-pot, to be cleaned. The receptacle B can also be removed from the tube 0, first removing c.

' By the use of this device, coffee can be made, extracting the strength without directly boiling the coffee, and clear cofiee can always be had.

The coffee-pot shown in the drawings forms no part of my invention, its only purpose being to aid in illustrating the operation of my attachmenttthough my device is to be used in connection with some form of cofiee-pot.

Having thus fully described my.invention,

What I claim as new, and desire to secure by Letters Patent, is as follows:

The herein-described apparatus, consisting of the tube 0, having the enlarged base A, with the perforated reservoir B and deflector cl, all constructed and arranged for use in an ordinary coffee-pot, substantially MARIN US DE GRAFF. Witnesses:
